lMPR-OVEMENT IN LAMP-BURNERS.

Speciication forming part of Letters Patent No. 118,193, dated August 22, 1871.

To all whom it may concern:

Be it known that l, GEORGE E. BRUSH, or" the town of Danbury, county of Fairfield and State oi Connecticut, have invented certain new and useful Improvements in the Construction of Lamps for Burning Kerosene Oil, of which the followin g is a speciiication:

hly invention relates to the arrangement of a double burner, two cones and two wicks, which pass down two tubes into the body of the lamp and kerosene, with two arrangements for raising and lowering the wicks separately.

Figure 1 is a sectional view ot' the cone and tubes and the arrangement for raising and lowerin g, and the manner in which the wicks enter the lamp. Eig. 2 represents the horseshoe or U- shaped form ofthe lower ends of the tubes as they are curved to enable them to enter the single oriice of the lamp-top, and to keep the two wicks apart so that they can rise or fall separately by the action of the two toothed wheels.

The lamp-top A is formed with the screw part B to screw, and to i'it on the usualfornled attachments of the common kerosene lamp. The cones C C are permanently soldered to the perforated upper plate D. This upper plate D is hung with a hinge, E, to the under plate F for the purpose oi being lifted up when required t0 trim thewieks, and is fastened down by the spring-catch G. The lower plate E is constructed and arranged to receive the two short, square, inclined tubes I I,

kerosene..together through the one hole, but independent of each other, and are each separately raised or lowered by the toothed Wheels K K. The perforated air-chambers N N are attached to the under side ofthe plate E, and surround each of the tubes7 and connect to the screw-top B of the lamp. The two tubes I I are beveled at the top ends, and arranged in a line with and inclined toward each other, and have their upper portions flattened and the lower ends bent into a horseshoe or U-form, (see Eig. 2,) for the purpose of compressing them small enough'to pass down through the single hole of the lamp-top.

The advantage ot' having the two tubes in a line and their ends being beveled is that it gives a broader flame and increases the brillianey.

The plates D H may be ma-de of an oval shape to receive an oval chimney, or any other suitable shape if required. I

The utility of my double-burner lamp in one glass chimney is in its economy, with the advan tage of a more brilliant light from a single lamp by a wider'eXpanse of tlame without increasing the heat in proportion to the brilliancy.

What I claim as my invention is* The wick-tubes l I, arranged in a line with and g inclined toward each other, and having their upper portion lattened and the lower portion bent Vinto a horseshoe-form, in combination with the
